Abstract
Keratotic and squamous changes characteristic of vitamin A deficiency were minimal even in chicks which were malnourished and growth stunted and had no vitamin A in their diet. However, when these chicks were infected with Newcastle disease virus (NDV), keratotic changes appeared, most markedly in areas regenerating after infection. In chicks raised on full nutrient diets lacking only vitamin A, keratotic changes appeared in several areas of nasal mucosa but were absent from the mucosa of the inner (under) surface of the maxillary turbinate. Following NDV infection, such changes did appear in the inner lining epithelia. It is suggested that depletion of vitamin A causes regenerating epithelial cells to keratinize. Other effects of combined lack of vitamin A plus NDV infection were exhaustion of lymphoid cells from cranial bone marrow and exhaustion of lymphoid cell systems locally from the nose and paranasal glands.
